Abraham Bosse’s book mainly consists of architectural illustrations, so we don’t find paragraphs of text on every page. However, each chapter offers a beautifully written introduction with decorated initials. Some titles are decorated with frames, ornaments or other illustrations. They are written in capital letters and the text itself in italics. The font seems to be a very classic serif from that time with some dynamic flourishes every now and then. Within the architectural illustrations, Bosse used capital letters to describe important things such as column types or their features. Other descriptions are written in the same italic font and rather small. Since almost every illustration also shows his measurements, you will find a lot of numbers. The most complex presentation of text probably is the title of the book. This might not be a surprise. It is designed to look like a heavily decorated stone tablet in front of a precious piece of architecture. Engraved on it is the title of the book, further details of its content, the author and where it was published. Another remarkable section of typography is the author’s conclusion on the last couple of pages. The title is framed and surrounded with decoration. As for illustrations, Bosse presents almost every type of them. There are many architectural drawings and perspective views with explanations and measurements. They are incredibly detailed and beautifully done. This supports a three dimensional appearance and makes them look like a photograph. You will also find a lot of geometrical sketches to understand the construction aspect of architecture. These can be very abstract and look quite complex at times. Many illustrations make use of one whole page, sometimes even more. They leave some space for explanation or commentary. Other graphics are spread over one page and kind of woven between paragraphs of text. Bosse really used different types of presentation of words and illustration. As far as I can tell, the illustrations are numbered. But there’s no directory or anything at the end of the book. Most of these numbers are references to an explanation or commentary close by. In general, images occupy most part of the book. I would consider it to be a study that also serves as a handbook.
